The only reason why it can be impossible is if the amount of compute needed to run one smart-as-smartest human model is so huge that we need to literally disassemble Earth to run 100000 copies. It’s quite unrealistic reason because similar amout of compute for actual humans fit an actual small cranium.
Did you misunderstand my question?
How does the total mass of the Earth or ‘signal speed 1000m/s instead of 100m/s’ demonstrate how you know?

Why is the amount of matter in a human brain relevant?
